Last November I wrote an article looking at the many similarities between airlines and telecoms firms. Both industries consist of carriers serving routes on a global network. Both were dominated by state-owned monopolies that have now mostly been privatised, but remain sources of national pride. All of which suggests that telecoms, like airlines, ought to be vulnerable to attack by low-cost carriers. This article was read by Stelios Haji-Iaonnou, the serial entrepreneur behind easyJet, a low-cost airline, and he decided this argument made sense. So he is now setting up easyMobile, an idea he freely admits he got from my article.
